*boggle*

I started to patch the vim one and... it already supports this? It won't produce
header/footer output for stdin:

$ echo "look ma no header/footer" | xxd -i
  0x6c, 0x6f, 0x6f, 0x6b, 0x20, 0x6d, 0x61, 0x20, 0x6e, 0x6f, 0x20, 0x68,
  0x65, 0x61, 0x64, 0x65, 0x72, 0x2f, 0x66, 0x6f, 0x6f, 0x74, 0x65, 0x72,
  0x0a

And both the busybox and toybox ones already get this right?

We can still add -I if you like, but... seems less vital now? More like a
documentation update.
